You are now in California and the U.S. category.

Flood water from the Sacramento River will continue to be a concern for residents along the river as the U.S. Bureau of Reclamation releases 79,000 cubic feet per second from Shasta Dam for the next couple of weeks. The Shasta County Sheriff’s Office says residents along the river should be aware of rising flood water. The Redding and Anderson Police Departments will be working with the California Highway Patrol, Redding Fire Department and the California Department of Forestry and Fire Protection as flooding occurs.

At 770 feet, the Oroville Dam is the nation’s highest. At 48 years old, it’s certainly not the nation’s newest dam. It’s important to keep that fact in mind as crews work around the clock in an attempt to reinforce the dam’s damaged emergency spillway before the next round of rains begin later this week in Northern California. The Oroville Dam, like many of the dams, levees, seawalls, and other human efforts to contain nature, is a crucial piece of infrastructure that must be maintained and monitored.

Inspectors visited Oroville Dam 14 times since 2008 but never considered the integrity of the hillside that eroded below the emergency spillway, leading to a near catastrophe that forced the evacuation of nearly 200,000 people downstream, state records show. The inspections by the state’s Division of Safety of Dams repeatedly mentioned the concrete apron, or weir, at the top of the emergency spillway, and often included photographs of it. “The structure was stable appearing, and the concrete remains sound,” inspectors wrote after their latest visit to the state-run dam in August 2016.

California is expected to officially start up its second desalination plant in April, which takes seawater and makes it potable. The first one opened in December 2015 in Carlsbad that is near San Diego while the next one will be in Santa Barbara that is north of Los Angeles. And 15 more are on the table there. Is this a global solution for the billions without access to potable or sanitized water? Can desalination be done in a way that is minimizes harm to the ocean and that uses clean energy to run its operations?
